lifting high lamp at the bottom of the rectangular cavity in the body, in addition to the electrical control system' Electrical control system generally referred to as the secondary control circuit electric equipment, different devices have different control loops, and high voltage electrical equipment and control way of the low voltage electrical equipment is not the same. 】 , but also installed the motor hoist system. Electrical control system installed inside the light pole, can avoid outdoor environment result in lifting movement failure. Electronic control system is equipped with all kinds of circuit overload protection device. System is widely used in copper, silver plated to ensure good contact with electrical connection. Lifting system is composed of motor, lifting high lamp ( Electromagnetic brake) Worm gear reducer 【 Worm gear reducer can also be called a worm gear reducer, new spare parts must be changed during used the running-in and load test before the formal use. 】 The safe coupling, Safety coupling ( Also called a torque limiter, torque limiter, safety clutch) , is one of the connection machine actively and work pattern in parts, the main function of overload protection, torque limiter is when required due to mechanical failure or overload torque than the set value, it is in the form of sliding limit the transmission of torque by the transmission system, after the overload situation disappear on its own recovery. 】 , main assist steel wire rope, wire rope, rope and pulley block. Worm gear reducer self-locking ability strong, compact transmission, the transmission ratio. In order to reduce the worm gear and worm' Worm and worm wheel mechanism is used to transfer between two alternating axis movement and power. 】 Speed ratio [ Ratio ( 速度比) An automobile drive axle of the main reducer gear ratio, it is equal to the rotation of the shaft angular velocity than half axle shaft rotation angular velocity, also is equal to the speed ratio of them. 】 Rising, reduce torque, especially pulley increases a set of activities, make the light speed is less than 0. 2m/s。 Lamppost main wire rope through the rope connected to the lamp panel auxiliary steel wire rope, avoided because of the main wire tension and make the auxiliary wire winding. Main wire rope with high strength and corrosion resistance of 6 * 19 not rotating galvanized steel wire rope. Lifting pulley block using A3 steel bracket, stainless steel shaft, copper pulley by the hot dip galvanized 【 Compound and the iron substrate reaction was to make the molten metal and alloy layer, so that the substrate and coating combination of both. 】 Processing, to ensure the normal atmospheric conditions not rusting, flexible motion. All kinds of fasteners, washer, card buckle parts are hot dip galvanized or stainless steel parts. Lamp plate is equipped with six set of guide pulley block and more than three sets of brake devices 【 Brake device ( Braking equipment) Is car furnish all the brake and the floorboard of the gear system, its function is to make the running automobile reduce speed or stop driving, or keeping the car has stopped, due to the structure and properties of braking device is directly related to the vehicle and personnel safety, and therefore is considered to be important safety car parts, brought to the attention of the general. 】 。 Lamp plate lifting process, the 120 - degree distribution of the surface of the roller along the light pole rolling, to ensure the lamp panel not swing. Lamp plate roller working parts and the surfaces of the light pole rubber extrusion technology. In order to fully guarantee the lamp panel reaches the limit position automatically stop, lamp plate lifting movement limit switch with reliable performance, and is equipped with distance protection. The rise and fall of high lamp panel is implemented by changing the direction of rotation of the motor. To be on the safe side, rectangular cavity is equipped with sealed door, with a special door lock
